SPENCER OTIS ANDGEORGE B. MALTBY, OF CHICAGO, ILLINOIS, ASSIGNORS TO NATIONAL COAL DUMP CAR COMPANY, OF RAPID CITY, SOUTH DA- KO'IlA, AND CHICAGO, ILLINOIS, A CORPORATION OF SOUTH DAKOTA.

AMETAL o SPECIFICATION forming'part of Letters Patent No. 744,224, dated November 17, 1903. Application filed January 5, 1903. Serial No. 137,921. (No model.)

To all whom it may concern.-

lie it known that we, SPENCER vOTIS and GEORGE l5. MALTBY,citizens of the United States, residing at Chicago, county of Cook, 5 and State of Illinois, have invented'certain new and useful Improvementsin MetalDump- Cars,of which the following is a specification. This invention. relates to that class of cars known as dump-ears -that is, cars used for :o the carrying of coal and similar materials which may be dumped ordischargcd through the action of the car-bottom portions, and it has particular reference to the construction and arrangement of parts, all of which will more fully hereinafter appear.

The principal object of the invention is to provide a simple, economical, and efficient metal dump-car of such construction and arrangement as will enable it to withstand the :0 stress and strains incident to ordinary use.

Further objects ofthe invention will appear from an examination of the drawings and the following dcscription'andclaims.

'll'ieinvention consists principally in a metal car in which there are combined a center sill formedot' llanged side members, aplurality of strengthenirig-pieces inserted therebetween,

and a plurality of cross-sills secured to and extending out from each side thereof. The invention consists, further, in the lean tures, combinations, and details olconstruc' 40 looking in the direction of the arrow; Fig. 5,

a similar view taken on line 5 of Fig. 1 looking in the direct ion of the arrow; Fig. (i, an

enlarged cross sectional elevation taken on line (5 of Fig. 1 looking in the direction of the arrow; Fig. '7, an enlarged sectional detail taken on line 1 of Fig. I looking in the direc-' tion of the arrow; and Figs. S and .J, enlarged sectional details taken on lines 8 and 9, re 1 spectively, of Fig. 1. In the art to which this invention relates it well known that it is Very desirable to provide metal cars of such construction and arrangement that they may be formed as largely as possible of commercial structural iron or metal-that is, iron or metal which may be purchased in the pen market and which as a consequence saves largely in the time necessary to construct a car and in the expense of materials, both as to original construction and repairs.

The principal object, therefore, of this invention is to provide a simple, economical, and eflicient metal carwhich will distribute throughout the entire supporting frame or dent to usage and formed of such structural materials as may be obtained through the ordinary commercial channels, all of which will be understood and appreciated by those skilled in theart.

In constructing a car in accordance with these improvements I provide a carframe whose principal member is a center sill extending longitudinally the entire length of the car and to which the underframing or supporting structure of the car is secured. This center sill is formed of a pair of metal side members having web portions a, outwardlycxtending. lower flanges b, and inclined inwardl y and upwardly extending upper i. anges c. These side members are secured together by a plurality of flanged metal portions (1, e, and 1'', which are riveted thereto and arranged at points opposite the crosssills and bolsterfillers hereinafter described, and a plurality of lower tie-pieces 1?, having arched inner web portions and seen red to the lower flan ges of the side nembers. The center sill is alsb provided with an A-shaped metal cap por- I strengthening-pieces and extending longitudinally thereof, with its lateral depending edges extending downwardly and outwardly from the sill proper for other securing and strengthening purposes, as will more fully 5 hereinafter appear. To provide for the economical and cl'iicient strengthening of the frame, a plurality of cross-sills his provided, formed of metal channel-pieces. (Shown par- 1 ticularly in Fig. 9.)

structure thereof the stress and strains inci- 65 tion g, riveted thereto and to the interposed 9o These cross-sills are 0011- Ice nected with the web portions of the side sills and extend outwardly from the outer sides thereof to'the extreme outer side of the car and, as shown inrFigs. 4 and 6, are substantially parabolic in shape. In order to provide for a portion of the filler-sections of the car and for a tapered or wedging joint for the swinging doors; hereinafter described, each cross-sill has a metal channel-beam j, having downwardly and inwardly inclined flanged portions straddling the upper part of each. as shown particularly in Figs; 3 and 9. These cross-sills, as well as their flanged caps,

' are secured to the A-shaped central portion of the sill by means of a plurality of strips 70.

(See Fig. 6.) To further provide for the underframingof the car, a body-bolster Z is passed under and secured to the lower flanges of the center sill, and interposed between the,

upper surface thereof, the floolf section of the car, and the center sill on the outer sides of the car is a subbody bolster or filler formed in two sections and by means of channelpieces m,-the lower and upper flanged portions of whi'ch are formed of angle-irons secured to the web portions, to the body-bolster, and to the deck-section, as hereinafter set forth. The deck or floor sections of these subbodybolsters are formed of ametal channel portion m, provided with downwardly and inwardly extending flanged portipns, which are also secured to the A-shapedpbrtion of the center sill. 1

In order to provid'emeans for dumping coal or other material carried in the car, a plurality of swinging doors 0 is provided, hinged at their inner ends to the sill portion and provided with lateral edges inclined downwardly and outwardly,' as shown in Figs. 8

and '9, to form atapered joint where such doors meet the deck or floor-sections proper.

To make a satisfactory hinge for such doors an integral metal plate is provided, formed of a body portion q, split so as to form an upwardly-extending integral center portion 0, wich is riveted to the under surface of the A-shaped sill-cap, as shown in Fig. 6, and withloop portions sat each lateral edge, forming eyes for the pivot-pins t. It will be seen, therefore, that these hinges not only'form the usual hinge, but also a strengthening-brace for the parts described.

To provide satisfactory end sills for the distribution of the stress'and shocks incident to use, U -shaped metal members 10 are provided, with their flanged portions 1; extending inwardly toward the center sills, to which they are secnredn Arranged outside of these end sills are the buffing-blocks or dead-wood w, reinforced'at the lower portion by means of the angular plates :10. car, vertical side boards y and e'n'cl boardsz are provided, made of commercial metal plate, and to hold these side and end boards in position aplurality of side posts 10 is provided madeof flanged metal of any desired cross-section and secured to the upper por- To form the box of the.

tions of the cross sills and to the inner face of the side sills, while a plurality of end posts Ibis provided and secured to the end sills and to the outer faces of the end boards, all of which. insures the satisfactory distribution of the strains and the holding of the freight material in the box-compa'rtm.ent.

To provide for further bracing the inner ends of the car, an inclined brace 12 is provided, formed of metal plates secured to the lower inner ends of the end boards and to the inner upper ends of the end sills, as shown particularly in Fig. 3, which acts as a satisfactory brace to the parts and assists-somewhat in the dumping or discharging of the material.
